Product Overview
Specially designed for large-scale production of polyurethane rollers for vacuum equipment, widely suitable for vacuum coating, vacuum drying, vacuum conveying and other precision vacuum equipment.
This PU elastomer casting machine is purpose-built for the large-scale production of polyurethane rollers used in precision vacuum equipment such as vacuum coating, vacuum drying, and vacuum conveying systems. The 1A1B independent temperature control two-component system supports flexible switching between MOCA and BDO chain extenders, allowing balanced optimization of high wear resistance and high resilience to prolong roller service life. The high-equipped vacuum defoaming system (≤-0.098MPa) produces a dense, bubble-free rubber layer, greatly improving vacuum sealing stability. Dynamic full-range high-precision metering ensures uniform rubber layer thickness and smooth surface, delivering high sealing fit that ensures vacuum sealing effectiveness. With simple operation and efficient changeover, the machine is ideally suited for small-batch, multi-specification vacuum roller precision production.
Operation Workflow
Raw Material Preparation
Prepare CPU prepolymer and chain extender (MOCA or BDO) at the target mix ratio (MOCA: 100:8-11; BDO: 100:3-5), selecting the formula for the required wear and resilience balance.
Tank Loading & Independent Temperature Setting
Load prepolymer into Tank A and chain extender into Tank B; the 1A1B temperature control sets Tank A at 30-80°C and Tank B per formula (MOCA: 90-115°C; BDO: 25-50°C).
High-Vacuum Defoaming
Activate the high-vacuum defoaming system to reach a vacuum level ≤-0.098MPa, thoroughly removing bubbles for a dense, bubble-free rubber layer critical to vacuum sealing stability.
Precision Metering, Mixing & Casting
The PLC metering system (accuracy ≤±0.3% full range) dispenses precisely; the mixing head runs at 8000-12000 r/min, with pouring rate adjustable within 30-700 g/s for different roller specs.
